[Gr.] (Ornith.) A fam. of birds consisting of one gen. , containing one spec, the Guacharo, or Trinidad goat-sucker, a mottled brown bird, flecked with diamond-shaped white spots. It lives gregariously in caverns, and is distinguished from true goat-suckers by not being entirely (and perhaps not at all) insectivorous. Much valued for its fat by the Indians, but superstitiously dreaded for its weird habits. Venezuela, Bogota, Trinidad. Ord. Picariae.
